S. C. BUTLER COVER FOR INNERSOLES FOR SHOES Aug. 2, 1949.

REMOVABLE Filed June 19, 1946 IN V EN TOR.

Patented Aug. 2, 1949 UNITED STATES ATENT OFFICE REMOVABLE COVER FOR INNERSOLES FOR SHOES 3 Claims.

The object of my invention is the production of a removable, washable cover for a removable innersole for a shoe.

The habit or custom of wearing shoes over the naked feet, causes the innersoles of the shoes to become soiled and to give off an offensive odor. During Warm weather, the perspiration from the feet tends to make the innersoles of the shoes stick or cling to the feet, causing irritation and lack of comfort.

My invention provides an easy and efficient method of keeping the feet clean and comfortable when Wearing shoes without stockings or socks. It also enables the shoes to be kept clean and sanitary.

The cover, as designed, has the further advantage of not being visible when worn with toeless and heel-less shoes.

In the accompanying drawing wherein I have illustrated one embodiment of my invention, Fig. 1 is a bottom view of an innersole with the cover applied. Fig. 2 is a perspective view, looking at the bottom of the cover and showing the innersole being inserted therein. Fig. 3 is a perspective view showing the top of the cover or the part that comes into contact with the foot. Fig. 4 is a longitudinal section of a heel-less and toe-less shoe showing the foot and innersole cover in place. Similar numerals refer to similar parts throughout the several views.

The cover I, is preferably made of a smooth washable fabric such as cotton, linen, rayon or nylon, either woven or knitted, or plastic material such as Geon, Polythene or plastic laminates and consists of three parts, the upper surface 2, conforming approximately to the shape and size of the innersole of the shoe, a toe piece 3, secured to the under side of part 2, to form a pocket for the retention of the innersole, and a heel piece 4, fastened to the under side of part 2 in such a manner as to allow the insertion and retention of the innersole.

The edges of the three pieces forming the cover are bound with a bias strip and are sewed together as shown at 5 and 6. It will be noted that part 4 is only fastened part way around the heel portion of the cover, leaving the front end free to insert the cardboard support or innersole.

As shown at I, Fig. 1, the free end of part 4 is tapered to a blunt point, which prevents this part from showing, in case it should shift sideways while being Worn.

The innersole 8 may be made of thin cardboard impregnated with a suitable compound to make it waterproof and durable, or of plastic laminates, thin leather or any other suitable material.

The purpose of the innersole is to keep the upper surface 2, of the cover taut and free of wrinkles.

While the drawing shows and the specification describes a cover made of a multiple number of pieces sewed together, be it understood that the cover could be knit in one piece or could be formed in one piece by plastic moulding, or could be made of paper or like material to be worn once and then disposed of.

I claim:

1. A removable inner sole cover comprising a continuous cover coextensive with the top of an inner sole and having toe and heel pieces peripherally attached to said cover, said attachment being discontinued through the portion of the inner sole underlying the wearers instep.

2. An inner sole assembly comprising a flexible form sustaining member shaped to conform substantially to the inner sole of a shoe, a removable cover therefor extending over the entire upper surface of the flexible member and having pockets adjacent its ends terminating short of the instep portion of the flexible member receiving the ends of the form sustaining member.

3. An inner sole assembly comprising a flexible form sustaining member shaped to conform substantially to the inner sole of a shoe, a removable washable fabric cover therefor extending over the entire upper surface of the flexible member and having pockets adjacent its ends terminating short of the instep portion of the flexible member receiving the ends of the form sustaining member.
